Well let's take a look at California specifically. There is an estimated 650,000 illegals in that state. California also has made it legal for illegals to obtain a drivers license (can't quite get my head around that).
Now it is my understanding that in most places you simply have to have an state issued ID and an addresss to register to vote. (I'm not clear on how it works in CA).
Now while I understand it is not LEGAL to vote if you are not a citizen, an illegal immigrant now has all the tools they need in order to vote.
Of course they would never do anything illegal, especially when the candidate they are voting against is threatening to kick them out of the country.
You're right. Stupid of anyone to consider that a possibility. My apologies, carry on.
